CVE-2022-1048

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.

The Linux Kernel, the operating system core itself.

The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes.(CVE-2022-1158)

KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered. CVSS 3.1 Base Score 6.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H).(CVE-2022-21499)

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

This kernel update is based on upstream 5.15.32 and fixes at least the following security issues:

An out-of-bounds (OOB) memory write flaw was found in the Linux kernel’s watch_queue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system (CVE-2022-0995).

A flaw use after free in the Linux kernel FUSE filesystem was found in the way user triggers write(). A local user could use this flaw to get some unauthorized access to some data from the FUSE filesystem and as result potentially privilege escalation too (CVE-2022-1011).

A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem. This flaw allows a local user to cause an out-of-bounds write issue (CVE-2022-1015).

A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c: nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker (CVE-2022-1016).

A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2022-1048).

st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c has EVT_TRANSACTION buffer overflows because of untrusted length parameters (CVE-2022-26490).

There is a buffer overflow in ESP transformation in net/ipv4/esp4.c and net/ipv6/esp6.c via a large message. In some configurations, local users can gain privileges by overwriting kernel heap objects (CVE-2022-27666).

A refcount leak bug was found in net/llc/af_llc.c (CVE-2022-28356).

Other fixes in this update:

• locking/lockdep: Avoid potential access of invalid memory in lock_class
• mm: kfence: fix missing objcg housekeeping for SLAB
• net: ipv6: fix skb_over_panic in __ip6_append_data
• rtw88: Add support for Realtek 8821CE RFE Type 6
• revert: "swiotlb: rework 'fix info leak with DMA_FROM_DEVICE'" as it breaks atleast ath9k
